REINFORCE.

SPECIFICATION forming part of Letters Patent No. 767,932, dated August 16, 1904.

Application filed July 8, 1903.

To aZZ whom it may concern:

Be it known that I, J OSEPH F.FRANorA,a subject of the King of Great Britain, and a resident of Paris, France, have invented a new and Improved Reinforce, of which the following is a full, clear, and exact description.

The invention relates to masts, spars, ladders, furniture, sporting goods, such as fishing-rods and oars, and other articles capable of breaking; and the object of the invention is to provide a new and improved reinforce which is simple and durable in construction, easily applied, and arranged to give the arti cle great strength and rigidity to withstand heavy strains without danger of breaking or imparing the substance, shape, or strength of the article.

' The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

. forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in the several views.

Figure 1 is a perspective view of the improvement. Fig. 2 is an enlarged sectional plan view of. the same on the line 2 2 of Fig. 1. Fig. 3 is a sectional side elevation of the improvement, showing more particularly the fastening of the ends of the spring on the core,

the section being on the line 3 3 of Fig. 4. Fig. 4 is an enlarged plan view of the same. Fig. 5 is a sectional side elevation of a modified form of the same, and Fig. 6 is a plan view of another modified form of the same.

The core A of the article may be made of wood, cane, bamboo, or similar material, and on the exterior surface thereof fit strips B of steel or other flexible material, the strips extending throughout the length of the core A, and the strips are spaced apart, as indicated in Fig. 2, but symmetrically distributed around the surface of the core, so as to render the same uniformly reinforced in all directions. Certain articles may, however, be reinforced on one side or sides only by laying one or more strips on one or two sides only. The sides of the core A can be flat or slightly grooved, so as Serial No. 164.672. (N0 model.)

to allow the strip or strips B to lie firmly on its surface in a flat position. Elastic glue can also be used for this purpose. The strip or strips B are either carried over the end or ends of the core A, Fig. 6, or steel is used firmly secured there by first removing the temper by heating the steel, then bending it, so that the strip or strips take or acquire a shape suitable either to crop over, as described, or form V a kind or kinds of hooks B, which after such alterations of shape are properly strengthened by retempering and" are either inserted into the ends of the core'A, Figs. 1, 3, and 4, or doubled up, as at B to rest on a small shoulder A on the core, (see Fig. 5,) the strips being secured in that position by a special binding or a metallic ferrule or cap.

Thestrips B are held in place by a covering (l, of a fabric material, wound around the strips and the exposed surfaces of the core A, as plainly indicated in Figs. 1 and 2, and this covering C is locked in place by bindings D, of tape, cord, wire, or other similar flexible material.

Now by the arrangement described the core A is greatly reinforced by the flexible strips B, so that when the article is subjected to a strain it bends slightly in the direction of the strain, and when the strain is removed the strips B immediately flex the core A back to its normal position.

From the foregoing it will be seen that the flexible reinforce for the core A can be easily applied, and the reinforce is so arranged as to render the article exceedingly strong and rigid and fit to withstand heavy strains without danger of breaking or impairing the shape, substance, or strength of the article.

When in an absolutely dry condition, the article must receive two or three coats of elastic copal or other varnish. This prevents moisture from injuring the core or corroding the steel strip or strips. The ends of the core where the steel strip or strips are fastened in the way described can be protected by metal or rubber caps.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. A reinforced article of the character described, comprising a core, one or more strips placed lengthwise on the sides of said core, and secured at both ends to the core, a cover- I5 ing for the strips and the exposed surface of the core and spaced bindings for holding the covering in position, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub- 20 scribing Witnesses.
